Kuwonongeka kwa SC - Kusinthira Chikondwerero cha Chemistry:
SC Yowonongeka ndi zinthu zatsopano zopangidwa ndi zikopa zopangidwa, zopangidwa ndikugulitsidwa ndi fakitale yathu yachikopa. Zogulitsa zapamwamba kwambirizi zimapereka phindu lililonse lothandizira chikopa poyerekeza ndi othandizira polymer, kuphatikiza madzi abwino a polymer, kuphatikiza madzi abwino, mphamvu yakuthupi, yolimbikitsira chikopa, komanso chidwi chachikulu. Adapangira makampani opangira zikopa, sc yokhayo yosakanikira siosavuta kugwiritsa ntchito komanso imathandizira kuyamwa ... -
Njira Yopita ku 'Formaldeyde-UFT's " Malangizo a Amino Retin Secteniction
Zovuta zomwe zimachitika chifukwa cha ma formaldehyde omwe amapangidwa nthawi yopukutira yatchulidwa ndi ma tayi ndi makasitomala oposa khumi zapitazo. Ngakhale m'zaka zaposachedwa ndizambiri zomwe zimachitika mwaluso.
Kwa matope akuluakulu akulu ndi ocheperako, mawonekedwe amasuntha kuyesedwa kwa zokhuza zaulere zaulere. Mafuta ena amayesa gulu lililonse lachikopa chawo chomwe chatsopanocho chitsimikiziro kuti zinthu zawo zakwanitsa miyezo.
Kwa anthu ambiri pachikopa, kuzindikira kwa momwe mungachepetse zomwe zili kwaulere

Polymer Testing Of Ast okhala ndi Ultra Magwiridwe ndi 'Kulemera Kwanu' Kulemera Kwanu Malangizo Oyenera Abwino
Kulemera kwa polymer
Mu chikopa cha chikopa, chimodzi mwa funso lokhudzidwa kwambiri pakukambirana kwa zinthu za polymer ndichakuti, nyengo yomwe imapanga ndi mankhwala a micro kapena macro-molekyulu.
Chifukwa pakati pa zinthu za polymer, kulemera kwa maselo (kukhala olondola, olemera a polecular ali ndi micro-molecle zonenepa, zomwe zimakonda kuwonongeka kwa chikopa zomwe zingachitike endow.Zachidziwikire, malo omaliza a polima amagwirizana ndi zinthu zosiyanasiyana monga polymerization, kutalika kwamankhwala, kulemera kwa ma hydrocular sikungawoneke ngati katundu wa malonda.
Kulemera kwa maselo ambiri ogulitsa pamsika kuli pafupifupi 20000 mpaka 100000 g / Mol, zomwe zimapangidwa ndi zochulukitsa mkati mwake zimawonetsa katundu woyenera.Komabe, kuchuluka kwa zolemera ziwiri za zosankhazo kumachitika kunja kwa nthawiyo.

Kusanduka kowala kwambiri | Malangizo Oyenera Abwino
Nthawi zonse pamakhala zidutswa zina zazing'ono zomwe timapeza m'moyo wathu zomwe zimatipangitsa kumwetulira nthawi iliyonse yomwe timawaganizira. Monga nsapato zapamwamba kwambiri zoyera zazingwe mu nduna yanu ya nsapato.
Komabe, kumakusangalatsani nthawi zina kukumbukira kuti pakapita nthawi, nsapato zanu zomwe mumakonda sizikhala zoyera komanso zonyezimira, ndipo pang'onopang'ono ikadakalamba ndi chikasu pang'onopang'ono.
Tsopano tiyeni tipeze chomwe chiri kumbuyo kwa chikasu choyeraMu 1911 AD Dr. Stoisny yapanga buku lopanda buku lomwe limatha kusintha masamba tanin. Poyerekeza ndi masamba annin, zopanga tannin ndizosavuta kubala, zimakhala ndi katundu wonyezimira, mtundu wopepuka komanso kulowa bwino. Chifukwa chake yakhala ikukhala yofunika kwambiri pazambiri zokutira zaka zana zikuchitika. Mu ukadaulo wamakono wamakono, mtundu wopangidwa ndi tanin umagwiritsidwa ntchito pafupifupi nkhani zonse.
Chifukwa cha kapangidwe kake kake, kagwiritsidwe ntchito nthawi zambiri, zimatchedwa kuti snomen tanin, sulfonic tannin, yofatsa tannin, etc.

Pali mawonekedwe otchedwa Wang kungmizang mu mzera wa mkh. Pamene anali kutali ndi kachisi, anakhazikitsa sukulu ya malingaliro; Pamene anali mkulu wa makolo, anapindulanso mderalo; Dziko likadali pamavuto, adagwiritsa ntchito nzeru komanso kulimba mtima kwake pafupifupi kuti asakhale osakwatiwa ndipo amateteza dzikolo chifukwa cha nkhondo yapachiweniweni. "Kukhazikitsa chiyero ndi luso sikosankha kwachiwiri pazaka 5000 zapitazo." Nzeru zazikulu za Wang Zikumeza za kuti anali wokoma mtima pamaso pa anthu abwino ndi machenjera kwambiri pamaso pa zigawenga zachinyengo.
Dzikoli si mbali imodzi, nthawi zambiri imakhala hymaphroditic. Monga othandizira am'mimba amitundu pakati pa chikopa. Othandizira amtundu wa m'munda omwe ali ndi gulu lazithunzi komanso gulu la aminic mu kapangidwe ka mankhwala omwewo - pomwe PH ya dongosololi ndi malo a isoelectric pofika poyambira wothandizira. Wothandizira wofunga bwino saonetsa kapena kukhala wopanda tsankho;
Pamene pH ya dongosolo ili pansi pa isooelertric point, gulu la Anioeric la wothandizirana limatetezedwa ndipo limangoganiza zogwirizana, komanso mosemphanitsa. -
